I got the car started and it seems to be running fine but, i cant get my tacho to work. I metered across pin 10 on the edis and ground and im getting +12v on pin 10 same thing on pin 12. I thought it was supposed to be a negative voltage from pins 10 and 12. Anyone throw me some pionters please.

Are you using this with Megajolt? If so, there are some solutions to the tacho problem on their site...

Ive tried most of the wiring setups but to no avail. Im not even getting a rpm reading from the mjlj when connected to the puter. I think i might try to pick up a cheap tacho just to make sure the tachos not buggered.

what you could try it so hook up a LED light with a resistor in light

if it blinks then the signal is there.

Tks

dave i will get a spectrum analizer over to you in the next few daze

I can upload and download maps to the mjlj and it shows 14 degree ignition advance but nothing in the other 2 lower boxes. I think its buggered
